Hash SHA256 MAC

• File hash SHA256, to upload to the server cloud. IM lost...

  Yet once here, bother this time because I have a problem in Cryptography (which I've never really worked).

  Well, I have to create a hash SHA256 from any file I want to download from a web server in the cloud, why? Because one of the parameters of the header that make me: x-filehash - A SHA256 hash of the file.

  I googled on how to do it and I found two ways to perform this task, the first is the native (using the husha2.h library) and the second is a library called polarssl.

  When I go through polarssl I noticed it's almost equal to the native form, so I finished it by selecting husha2.h.

  The problem is that I don't know much about the 3 or 4 functions to create a SHA256 hash and less for an entire file. So I wanted to ask if a kind soul among most here, has a small example to use this library, but I at least to explain a bit what each of the settings and what would be the order in which you must use the functions.

  Thank you and sorry for the inconvenience.

  I tried the same sequence of calls you (I've hard-coded the HMAC key and input data) and I got consistent results every time. Here is my piece of code (I called once, the onInitSecurity() onMakeHash() several times and onEndSecurity() once) - I use emit message() to send to QML on my screen. Did you check the return codes from each call? I have SB_SUCCESS on them. Variables beginning _... are the ones class instance.

• compare 2 files for the same, but different

  I have 2 files TrueCrypt 7.1 Mac OS X.dmg and TrueCrypt 7.1 Mac OS X (2) the .dmg that compare with hash sha256 identical (04db58b737c05bb6b0b83f1cb37a29edec844b59ff223b9e213ee1f4e287f586) and compared with the help of the cmp command. The two compare properly.

  When I try to install 1 file I get the message "error truecrypt requires Mac OS X 10.4 or later", but the other recipes to install correctly. Why, if the files are the same?

  The problem was with the security and privacy settings. Because Truecrypt is not an application recognized by Apple, it concerned differently for one file on the other. I suspect because I had already tried to install the previous file.

• Help ID for rtmfp streams based video app

  In the article:

  http://www.Adobe.com/devnet/flashplayer/articles/rtmfp_cirrus_app.html

  I need help understanding the following section:

  " Now create the receiver NetStream:

  private var recvStream:NetStream;

  recvStream = new NetStream (netConnection, id_of_publishing_client);

  recvStream.addEventListener (NetStatusEvent.NET_STATUS, netStreamHandler);

  recvStream.play ("media");

  At this point, you hear audio and you can create a video object to display the video. To create the receiver NetStream, you must know the peer ID of 256 bits of the Editor (id_of_publishing_client). In order to receive audio/video, you must know the name of the stream being published. »

  ***

  I do not understand what "client id_of_publishing" is supposed to be?

  Where can I find where how do they produce? Is this string that the user can enter in a text field on the flash object and when two chains corresponding produces a connection between the two?

  Is there a system of hash I have to pass the string in to generate a 256-bit of a string that is entered peer id or use the one that is given to me through workshops for adobe?

  Y at - it report any with the creation of a network group?

  I have the dev_key and address cirrus to access the cirrus service provided by adobe, Im just stuck on the part ID that I can't quite understand the article, need a database to store and manage the ID in a simple application?

  Im trying to develop a very basic program that uses the examples provided in the article, rtmfp but Im stuck here, I would appreciate anyones assistance. In addition, I looked at the example of cirrus phone that uses the cgi file to manage identifiers but I find it still more painful with so I have resorted to make a very basic example that avoid to create an ID database or use my own FMS.

  Thanks in advance for your help.

  the "id_of_publishing_client" is the ID of the peer of the editor.  a peer ID is a unique identifier of encryption that has each instance RTMFP. It's the NetConnection.nearID of an RTMFP NetConnection object. the idea is that you use a method (for example a web service database or copy - paste between two windows on your development computer) to transfer the peer ID of a Publisher (a peer with a NetStream in DIRECT_CONNECTIONS mode) to a Subscriber for use in the NetStream constructor.

  Peer ID of a Flash Player NetConnection is the hash SHA256 of the RTMFP certificate, which contains (among other things) a Diffie-Hellman public key.  the public/private key pair DH is made fresh every time that you make a new NetConnection RTMFP on number Pseudo-aleatoires source cryptographic of your computer (example: / dev/urandom on Linux/Unix/Mac computers), and these keys are used (with other data) to create the encryption keys & symmetric decryption for AES, which allows to encrypt all communications between counterparts RTMFP.  a client peer ID is impossible to forge * because you must have the private key that matches the public key to generate the same AES keys that are using your peers. without the private key, the communication will work. implementation of the discrete logarithm of a public key of 1024-bit DH to get the private key or to find a collision to SHA256 is both "quite difficult" to claim that peer IDs are impossible to forge.

  How does Card Crypto knows what ISAKMP policy to use, or use of the ISAKMP policy at all?

  It comes from "ipsec-isakmp?

  I mean... I do not see any "set isakmp policy 10" in the Crypto map

  This is what he chooses just the top-down approach?

  As part of the negotiation of the phase 1 and is a top-down proposal based on the sequence number.  You can get the details in tunnel using configuration:

  Debug crypto ISAKMP

  Cisco IOS has built/strategies default ISAKMP, but the pre 15.x versions were terrible default.  New default values are strong, although I still like to configure them myself.

• Traffic is failed on plain IPSec tunnel between two 892 s

  Have a weird case and you are looking for some suggestions/thougs where to dig because I have exhausted the options.

  Note: I replaced the Networkid real to a mentined below.

  Topology: a classic IPSec VPN tunnel between two 892 s of Cisco, with pre-shared key and no GRE. A 892 (branch_892) has access to the Internet using PPPoE and has three network / VLAN behind it. A VLAN is coordinated to the PPPoE internet access. Access to the other two VLAN - VL92 (100.100.200.0/24) and VL93 (100.100.100.0/24) is performed via the VPN tunnel.

  Second 892 (892_DC) has just one interface - WAN on Gigabit enabled/connected and a static route to the default GW. It doesn't have any defined interal network. If the router is strictly used to send traffic to VL92/VL93 to the domestic 892 via IPSec tunnel.

  Here's the problem: access to VL93 (100.100.100.0/24) works, however for VL92 (100.100.100.0/24) - does not work.

  Devices in VL92 I ping IP address of 892_DC through the VPN tunnel. The 892_DC router I can ping devices in VL92. However, I can't VL92 ping any device beyond the 892_DC and at the same time the packets arriving on 892_DC for VL92 are not sent through the VPN tunnel.

  I took the package trace on 892_DC using capture point/buffer to nathalie caron to VL92 packages and saw that the traffic coming to the 892_DC. I run the nathalie caron even on Branch_892, and there was not a single package.

  So... What's the problem? More interesting, I modified the way left on VL92 access list and still - no packets are sent through the tunnel.

  Any idea? Two routers config are below

  Yes correct sounds - so another possible problem is the routing is routing 100% correct on both sides? Can you put the two sides config for review?

• VM simple Load Balancing with 4 physical network adapters

  I have one main server with 4 cards of physical network dedicated to this server in a vSwitch. I wanted to know the proper way to balancing configuration in vSphere to allow a theoretical throughput of 4 Gbit/s. The options I have, as you know:

  1. Port according to ID - this the method by default when you have 2 or more physical NIC connected to a virtual switch. The VM traffic is realized on a physical NETWORK card based on the VMs virtual port ID and is incremented in the style of round robin. So if you have 2 NICs physical network, the first drop of will traffic VMs that the first NIC, the second VM shuts down to the second NIC, third comes out first NETWORK card and operating system on - host ESXi does not resemble the traffic so if VMs 1,3,5 are heavy network users they will go on the same NETWORK adapter even if the second NETWORK card can be totally unused
  2. Address based MAC - based similar to port, but the physical NETWORK adapter is selected according to the MAC address of virtual machines
  3. IP hash database - the physical NETWORK adapter is selected based on the starting and destination IP address - so if a virtual machine connect to several IP addresses that traffic will be disttibuted on all physical network cards - note this will require LACp be configured on the physical spend this ost ESXi connects to

  The first two sound me as they would give me what I want from the physical NIC selection is based on the virtual source, not the destination machine. So, since I have only a virtual computer, the LB would never use a physical NIC and I'd be stuck with 1 Gbps.

  The third option seems more promising, but I do not have much exposure to the management switch. LACP would be similar to the creation of a trunk on my 3Com switch 2848 reference? It seems likely, but I wanted to run it by the experts to make sure.

  Thank you!

  EDIT: I think I just found the killer. Cited in the manual for my switch:

  The switch does not support the aggregation of links
  Protocol LACP (Control), which is specified in the IEEE standard
  802.3ad.

  Does that mean I'm desperate to do my 4 Gbps with the swithc and I MUST get a LACP switch?

  You will need either LACP or EtherChannel on your switch upstream to support IP hash configuration, install, configure, manage Volume 1 book for ESXi 5.0. With hash IP, MAC address of the virtual computer may appear on any of the physical interfaces available for the vSwitch (at least for the outbound traffic), which would cause problems on the side of the physical switch unless a method of aggregation (LACP or EtherChannel) link type is enabled.

• confused about nearid, farid, nearNonce etc.

  I'm confused on different ID

  NearId equals farid on the other end

  What is nearNonce id

  I found an explanation of the high level architecture that beautifully explained how P2P works all in all.

  Are there more articles with a detailed explanation of how all pieces fit the puzzle together?

  Thanks for the help

  A book that guides me through various puzzle pieces would be a blessing. Is there any book of Cirrus over there?

  the event.info.neighbor is the address of 'group' of the neighbor.  event.info.peerID is the ID of the peer of the neighbor. You can convert ID equal to a group address, but not the reverse, as the group address is a hash SHA256 of the ID of peers (and other data).

  Currently I see many MAC beat in the log of the switch.  From my understanding, I expect the MAC address out all ports, because that's what'd ESXi when you use 'route based on the hash of the IP.  I'm worried about the impact this might have on the CPU / switch.

• SHA256 Encryption in Blackberry

  I'm looking for SHA encrypt a string value in the BB, but some of the classes BB shows some samples which returns the length of the hMAC

  That is to say,

  private static int sampleSHA256HMAC (byte [] hashKey, text of byte [], byte [] digestData)
  throws CryptoException, IOException
  {
  Create the hash key function key
  HMACKey key = new HMACKey (hashKey);

  Create an instance of a HMAC
  HMAC hMac is new HMAC (key, new SHA256Digest());.
          
  Now, create the output stream of MAC for easy use
  MACOutputStream macStream = new MACOutputStream (hMac, null);
                  
  Write the text to the stream
  macStream.write (plain text);
          
  Copy the summary in the array of bytes digestData data and
  Returns the length of
  hMac.getMAC (digestData, 0);
  Return hMac.getLength ();
  }

  Is it possible Sha encrypt a string to return a string value (hash value) of the string as string itself.

  Hello.

  If you consider what peter_strange said to not be an encriptación algorithm and you want to continue using it, try this method. It returns a string

  private String sign(String content) throws Exception {
    HMAC sha256 = new HMAC(new HMACKey(secretAccessKey.getBytes()),
      new SHA256Digest());
    sha256.update(content.getBytes());
    byte[] signed = new byte[sha256.getLength()];
    sha256.getMAC(signed, 0);
  
    String signedbase64 = Base64OutputStream.encodeAsString(signed, 0, signed.length, false, false);
  
    return signedbase64;
  }
  

  Well, it actually returns a URLUTF8 Encoder Base64 string version but you get the idea.

  The secretAccessKey object is a string needed to chop your content. I guess that you will place your own key here.

  In summary:

  -Create the HMAC object using your key.

  -Fill with your content.

  -Create a byte [] to place the hash.

  -Complete the table with the ground content.

  -Convert the bytes to a string (I used the base-64 but I guess you could just use String (byte [])) new

  I hope it helps.

  See you soon.

• The incognito in 39 of Firefox for Mac does not work

  When I connect to Gmail with Firefox for the Mac sha256 39 - 7da80d615390fc65f0f5540ac2fbaa6e5d8e8e0b and close the tab, then immediately open gmail again it automatically logs me on my same Gmail account if I use private browsing.
  Private browsing is not suppose t maintain all information so how is able to access my Gmail account without my entered password?

  I don't know how the private browsing mode works on Mac because you can close all the tabs, but still operating application Firefox (the menu bar is here), so it is likely that you have not finished the session mode PB.
  You will need to close and restart Firefox to get rid of cookies that make the site remember you.
  Closing tabs does not seem to be enough.

• My Mac Pro 2013 will sleep is no longer

  A month or there is my Mac Pro 2013 is no longer sleeps, even if I try to sleep it manually. I have enabled and changed the setting of Sleep/Power Nap in energy-saving.

  I looked at the article Apple and that did not help. I have reset the SMC and booted without failure. I haven't changed any connected equipment or internal. The console log does not help me, but here's the most recent when I sleep manually it. I have bolded the line that started the sleep/low power mode and the line where it was released

• Mac Mini Late 2012 restarts randomly

  I use a Mac Mini Late 2012 (standard loadout MD387 except for an upgrade to 8 GB of RAM) as a small home server.

  It is essentially:

  Plex Server

  File server

  Print Server (AirPrint incl.)

  TM Server

  VPN server

  I would say that it is completely idle about 75% of the day.

  Every now and then it just restarts with the message: "your computer restarted because of a problem."
